Chapter 7 Linking and Synchronizing Models in PowerDesigner
You can create extended dependencies toward objects in models of heterogeneous types.
When you define an extended dependency, a shortcut of the linked object is automatically created in the current model. Inversely, a dependency is added to the target object. For example, you create an extended dependency in table Sale to entity Sale in a CDM: a shortcut of entity Sale is added into the PDM.
If you open the CDM that contains the Sale entity, which is actually the target object of the shortcut in the PDM, the link is displayed in the Shortcut sub-tab in the Dependencies tab of the entity:
In the Dependencies tab, you can use the impact analysis feature to verify how a change in a target object can affect linked objects.
For more information on impact analysis used with requirements and design objects, see the "Monitoring Links Using Impact Analysis" section.
